## **Product Overview**
The Daewoo bucket Hydraulic Cylinder is a core Hydraulic Actuator specifically designed for DAEWOO series excavators (such as DH220, DH300, DX series, etc.), used to precisely control the opening and closing movements of the bucket, directly influencing the efficiency and stability of excavation and loading operations. This product strictly adheres to the original factory technical standards, using high-strength materials and precise manufacturing processes to ensure a perfect match with DAEWOO excavators and provide outstanding durability and reliability.

### **Key Features**
#### **1. Original Equipment Compatibility**
- **Precise Matching**: Specifically designed for models such as DAEWOO DH220, DH300, and DX series. The installation dimensions and oil ports are 100% compatible with original factory parts, allowing for direct replacement without the need for modification.
- **High Performance Alternative**: Offers OEM-quality equivalent performance parameters (thrust, speed, pressure resistance) that fully meet the requirements of the original factory.
#### 2. Exceptional Durability
- **High-quality Materials**: The cylinder body is made of **high-strength alloy steel** (quenched and tempered heat treatment), and the surface of the piston rod is **coated with hard chromium** (thickness ≥ 0.05mm), which is wear-resistant and corrosion-resistant, suitable for harsh working conditions such as mines and gravel crushing.
- **Imported Seals**: The sealing system uses **German MERKEL** or **Japanese NOK** components, capable of withstanding high pressure (35 MPa) and resisting wear, effectively preventing internal leakage and external leakage.
#### 3. Efficient and Stable Operation
- **Buffer Design**: Buffer structures are incorporated at both ends of the cylinder to reduce the impact during the opening and closing of the bucket, protecting the Hydraulic System.
- **Low Friction Guidance**: Precisely machined guide sleeves ensure smooth movement of the piston rod and prevent jamming or crawling.
#### 4. Convenient Maintenance
- **Modular Design**: Offers a **maintenance kit** (including a complete set of seals), enabling on-site rapid maintenance and reducing downtime.
- **Dust Protection**: Multiple dust-proof designs (dust seals + dust-removing rings), preventing sand and dust from entering, and extending the lifespan of the cylinder.
